FEATURES & OPERATING CONTROLS

A. INFINITE SWITCH

1. On INFINITE SWITCH CONTROLLED warmers, power is
applied to the heating element based on the control knob
position, which varies the duty cycle of the heating element.

2. The desired temperature is controlled by rotating the
TEMPERATURE CONTROL KNOB. The knob may have a
numeric scale, where higher numbers correspond to higher
temperature. LO is the lowest temperature setting; PREHEAT
is a “continuous on” setting. Infinite switch controlled warmers

IMPORTANT:

“PREHEAT”

control, leading to premature
failure of the hi-limit control
device.

are equipped with a hi-limit device to prevent overheating. The
hi-limit will self-reset after the warmer has cooled.

3. On warmers equipped with an INDICATOR LIGHT, the light will
glow when the infinite switch is in any position other than OFF.

4. The TEMPERATURE CONTROL KNOB will rotate without
stopping, with PREHEAT and OFF having obvious detents.
The OFF position is a “positive” OFF (i.e. the switch is positively
held in the open position).

NOTE: An infinite switch controls temperature by varying the ratio
of "on" time to "off" time. Thus, no temperature sensing devise is
required.

B. MOUNTING

1. Top-mounted drop-in warmers are equipped with
WELLSLOKS, uniquely designed turnout tabs which help
secure the warmer top flange to the countertop.

2. See the Installation Instructions, supplied with the particular
appliance, for details.

C. DRAINS

1. “D” units (e.g. SS-10D) have drains for each well, with
each pan having an individual drain valve.
